Yes, I applied for AACOMAS's waiver the first of this month which I was fearing was too late. I'm confident I'd get it (I got AMCAS's for the MCAT last year)...But will not hold up my app for it as I'm not applying to THAT many DO schools to really warrant it...Thus, if I apply before hearing back it will just be voided and I'll be on my way, right? This is what the general instructions seem to say.
To the OP...on the aacomas page it tells you what you need to do...Tax forms, SASE, signed copy of SAR to the address I believe is all that it is. But do double check, it's easy to find.
